![]() ![]() I also liked the idea of the "battle boxes" that maximum motorsport or somebody like that was selling, they were basically a much thicker steel version of the rear floor where the UCA and LCA bolt in. I'm not a big fan of a tube going right through the driver's foot well. I think your idea of putting a tube inside the rear frame above the floor, then welding that to the top of another tube running under the floor into the front frame is a good one. I would also build into the SFC a driveshaft loop and an additional cross member tie in at the trans mount. Regardless of what else you do - run a 1x1 tube along the hem flange of the rocker / floor - it will make jacking up the car from that day forward a non issue - no more dented rockers, etc.įrom the "jacking rails" run some sort of bracing over to the SFC - triangulate it if you wish (think steel building truss) that will embrace your overkill gene and add considerable stiffness / rigidity to the chassis. Maybe not?įeel free to take me to school here guys! I'm not sure if a roll bar or cage will be called for - not sure it will ET low enough for that to be necessary, and I think I can get enough stiffness from the floor area alone. It was a real nice car too, darn shame it got outta shape. That thing was a Ton-O-fun.right up to the point where it tweaked the body and the doors wouldn't shut anymore. (some history here - helped a friend back in '88 put a 351 Cleveland and manual 3-speed in a Fox Mustang, cut to fit, paint to match deal. Maybe if I drive a piece into the rear subframe and then notch it to meet up with the straight piece at the kickpanel.hmmmm. its attaching it at the back where I'm undecided. I've basically decided to run the 2x2 all the way thru the front subframe like in #1. My gut tells me that adding the equivalent of an actual frame to the car will be enough to satisfy my needs. ![]() When you say to take the time to connect the rocker to the sfc, are you thinking just for a roll cage mount, or for the additional stiffness? I've seen the jacking rail you had, its a neat piece too. I do have a stong overkill gene that I have to keep an eye on, but they really just don't seem like they would do much. I actually have a set of brand new 1x2 underfloors with the seat brackets - they just don't inspire a lot of confidence to me when I take them out of the box and hold them in my hand. There is a lot of gimmicky stuff on the market for these cars (in my opinion) and he didn't seem to go for that. Whatever you do - take the extra time to connect the SFC to the rocker, are you going to add a hoop inside the car or a cage?Kenny Brown sure had some cool stuff that was well thought out. Through floor is likely better - but the under floors made a huge difference in my car, 'course - I didn't have cadzilla under the hood either. I also got his "jacking rails" which were welded into the seam of the rocker to the floors, then connected those to the 1x2 of the SFC. They were 1x2, with angle perpendicular to the tubing to attach two seat bolts to (I think it was the front seat bolts, not sure) As I recall they wrapped around the front of the attachment point for the LCA in the rear, and welded into the front subframe. I had underfloors on my '90 from kenny brown in Indy. There is even one where the entire front subframe is removed by drilling the spotwelds, then a straight piece of 2x2 is welded into a slot cut from the firewall at an angle and inserted into the rear subframe.Īny opinions? I am definitely going to do thru-floor SFCs, but where is the limit of strength-gained-per-effort? Then the 2 sections are welded together with a shorter piece.Īnother way cuts both the top and bottom of the front subframe open and inserts a single straight 2x2 which then simply butts to the rear seat kickpanel. I've seen them from the slightly offset style, where a 2x2 is dropped into the front subframe after it is cut open from inside the car, and a second piece of 2x2 is inserted into the rear subframe thru a hole cut into the rearseat kickpanel. And that doesn't even include the bolt-on or simple undercar weld-on versions!įor the purpose of this discussion, let's just keep it to the THRU-FLOOR methods. There seems to be as many ways to install subframe connectors on a FOX platform (mustang) as there are flavors of beer.
